Tochuina
''Tochuina'' is a genus of sea slugs, tritonid nudibranchs, marine gastropod mollusks in the family Tritoniidae.MolluscaBase (2018)''Tochuina'' Odhner, 1963.Accessed on 2021-01-06. Taxonomy The species composition of ''Tochuina'' was clarified in 2020 as a result of an integrative taxonomic study of the family Tritoniidae.Korshunova, T.; Martynov, A. (2020)Consolidated data on the phylogeny and evolution of the family Tritoniidae (Gastropoda: Nudibranchia) contribute to genera reassessment and clarify the taxonomic status of the neuroscience models ''Tritonia'' and ''Tochuina''.PLOS ONE. 15(11): e0242103. ''Tochuina'' differs from ''Tritonia'' in having a non-bilobed oral veil and the clade is supported by DNA phylogeny. An interesting finding was that the tritoniid genus ''Tochuina'' not only shows an intriguing morphological similarity to '' Doridoxa'' and '' Heterodoris'' but clusters close to these genera, which themselves cluster with the family Arminidae, in a molecul ...

Tochuina Gigantea
''Tochuina gigantea'', common name the giant orange tochui, is a species of sea slug, a tritonid nudibranch, a marine gastropod mollusk in the family Tritoniidae. Bergh (1879) used the name ''Tritonia tetraquetra'' in a sense different from Pallas (1788). The valid name for ''Tochuina tetraquetra'' sensu Bergh, 1879 is ''Tritonia gigantea'' Bergh, 1904.MolluscaBase eds. (2020)MolluscaBase. Tochuina gigantea (Bergh, 1904).Accessed on 2021-01-06.

Tritoniidae
Tritoniidae is a taxonomic family of nudibranchs in the suborder Cladobranchia, shell-less marine gastropod molluscs.MolluscaBase (2018)Tritoniidae Lamarck, 1809.Accessed on 2021-01-01 This family includes some of the largest known nudibranchs, with the NE Atlantic species '' Tritonia hombergii'' reaching 20 cm in length. It is the only family in the monotypic superfamily Tritonioidea. Distribution These nudibranchs occur worldwide in warm and temperate seas and in the coldest waters and deep sea, wherever the octocorals which they eat are found. Ecology Members of the family Tritoniidae feed on octocorals, including sea pens, alcyonarian soft corals, and gorgonians, often being cryptic in shape and colouration upon them.García-Matucheski, S. and Muniain, C.

Doridoxa
Doridoxidae, commonly known as doridoxid nudibranchs, are a small, enigmatic taxonomic family of shell-less sea slugs, marine gastropod molluscs in the clade Cladobranchia within the clade Nudibranchia. Doridoxidae is currently the only family in the superfamily Doridoxoidea, within the clade Pseudoeuctenidiacea (= Doridoxida). Molecular evidence shows that it groups with the genera ''Doridomorpha'' and ''Heterodoris'' and the family ''Arminidae'' and close to ''Tritoniidae''.Korshunova, T.; Martynov, A.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () " gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic '' Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Dist ...

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
